A receptacle having an inclosing wall formed of paperjcovered, saturated with, and having its pores filled with paraflin and oil of tar and having its ends formed of ladquered metal and crimped so as to turn the edges of the ends into the inclosing wall and roll inward.

In testimony whereof, I have hereunto slgned my name to this specificatlon in the presence of two subscribing witnesses.
